Why does the left hate free speech and why do so many people let attacks on free speech slide?

What we had yesterday was a coordinated attack on free speech. Notice how Twitter bans Trump, Facebook, Instagram and Twitch freeze his accounts and Youtube bans Steve Bannons podcast and remove Parler an alternative pro free speech network from the android app store?

People say "Trump in cited riots". Yet these same social media companies did nothing to remove hate speech from the left. If you dont believe me type the words "white people" into the twitter search box and see what comes up.
